The acceleration of gravity is 32 feet per second, per second. This means that --eliminating any obvious aerodynamic considerations as there would be with, say, a feather -- the speed at which an object falls increases proportionately to the time it is falling. An object falling from a greater height will be falling for a longer time period and thus will reach a higher velocity and impact the ground with a greater force than one falling from a lower height.
if an object is lightr it will fall slower because gravity wont take it down as fast if it is heavier it will make the gravity pull it down faster
If you have the equipment you can film the bounce with a height metric in the background so that the cameral will catch the object as it bounces up against the height metric (e.g., a meter stick). If the camera is really special and you can take slo mo pictures that's even better because you can see the exact moment the object reaches max height on the meter stick. A less precise method would be to time the fall from the max bounce height. In which case the height the ball fell from would be calculated as h = 4.9 T^2 where T is the timed fall in seconds and h is the bounce height in meters.
Galileo dropped two different sized objects from the tower of Pisa and they both hit the ground at the same time. The object was to prove that the size/weight (i.e. mass) of the object would not affect the rate of fall.
Distance and time do not, in general, affect the speed. Speed, however, can affect distance or time. Distance is directly proportional to speed, time is inversely proportional.
-- Take a heavy object and a stopwatch. -- Start the timer as you drop the object from the unknown height. -- Stop the timer when the object hits the ground. -- Read the time off the watch, in seconds. Square it. (Multiply it by itself.) -- Multiply that result by 16.1 . -- Now you have the distance the object fell, in feet.
Galileo
It won't affect the rate of fall, which is 9.8m/s2. If you drop a bowling ball and a crumpled ball of paper from the same height, they will land at the same time. The earth's gravity determines the rate of fall. During the Apollo 15 moon landing, a feather and a hammer were dropped from the same height and they landed at the same time. The moon's gravity determined their rate of fall. Refer to the related link to see the demonstration.
The mass of an object will not affect the time it takes for it to reach the ground from a fixed height. Backspace
Galileo galilei
The surface area, mass and the shape of the parachute affect the time of fall of the parachutes. Also the height, where the parachute have been dropped from. ( There are more factors that this).
You need the amount of time that it took to fall the 45m.
In a vacuum, they will fall together. Air resistance might have a minor affect on the results.
If thrown horizontal from same height the faster object will travel farther horizontally, but time to fall is the same. If thrown straight up, the faster object will take longer to fall
if an object is lightr it will fall slower because gravity wont take it down as fast if it is heavier it will make the gravity pull it down faster
On object falling under the force of gravity (9.8 m/s2) would, in a vacuum, fall a distance of 706 metres in 12 seconds. In a non-vacuum, i.e. air, the object would fall less distance in the same time due to drag.xt = 0.5 (9.8) t2
Before you test it, you could state the hypothesis in two different ways You could say: "The mass of a falling object has no effect on the time it takes to fall some distance." Or you could say: "The time a falling object takes to fall some distance depends on its mass." You could use the same tests to investigate EITHER hypothesis. --------------------------- The mass of a falling object has no effect on the time it takes to fall some distance assuming zero air resistance.
drop a heavy object and a light object from the same height at the same time. time it with a stopwatch, or just watch them.
